Make core.current.stubs a proper subset of android.jar

Previously, this was built against a different set of classes than
the core library contributed to the android.jar and so there were some
differences.
1) Some com.android.org.conscrypt annotation classes were accidentally
   exposed due to a bug in the currysrc code that meant it did not
   process annotations.
2) The android.net.ssl classes provided by conscrypt were not present
   because that are in a separate conscrypt_public_api_files filegroup
   which was not supplied to droidstubs

Test: m checkbuild and check stubs output
